不同肥水调控下醋糟菇渣在黄瓜栽培中的优化配比研究

Optimization of Vinegar Residue and Mushroom Dreg Ratios for Cucumber Cultivation under Various Water-Fertilizer Controlling Measures

在不同配比的醋糟和菇渣复合基质中,通过对水果黄瓜的不同肥水调控,以株高、叶龄、叶绿素、植物营养及产量等为指标,优化栽培方式。结果显示:①100%清水灌溉下的各配比复合基质黄瓜产量均显著低于对照,表现出了明显的肥力不足;②100%营养液滴灌下的各配比复合基质,黄瓜产量略高或略低于对照,但肥力水平过高;③50%清水+50%营养液肥力水平下,60%醋糟+40%菇渣配比的复合基质处理肥力水平比较适宜,黄瓜产量为对照的98.2%,差异不显著,因此,该基质配比及其肥水调控方案可作为黄瓜栽培的最优方案。

The cultivation method for cucumber was optimized by the experiment of different ratios of vinegar residue and mushroom dreg under various water-fertilizer controlling measures. The results showed that： ① the various substrate compositions with 100% clean water irrigation expressed the lack of fertility, and the yields of them were significantly lower than control; ② the various substrate compositions with 100% nutrient solution irrigation expressed excessive high fertility, the yields of them slightly higher or slightly lower than that of control; ③ the treat of 60% vinegar residue ＋40% mushroom dreg with 50% clean water ＋50% nutrient solution irrigation had an appropriate fertility level with 98.2% yield of the control, and the difference between their yields was not significant. So this treat was the optimal solution for cucumber cultivation.
